3 M66291 OPERATIONS
3.1 Interrupt Function
There are 8 factors of interrupts in the M66291.
For details, refer to the “Interrupt Status Registers 0 to 3”.
The enable/disable of interrupt can be set by the Interrupt Enable Registers 0 to 3.
Each bit of the Interrupt Status Register is set to “1” according to the factor even if the Interrupt Enable
Registers 0 to 3 are set to interrupt inhibit mode.
The list of interrupts in M66291 is given in Table 3.1 and the diagrams related to the interrupt in Figure 3.1.

occurred interrupt by the EPB_RDY bits of
the Interrupt Status Register 1.
